How often to Change Synthetic Blend Oil? [Explained]

Synthetic blend oil is a mixture of conventional oil and synthetic oil. This type of oil can provide better protection for your engine than conventional oil, and it can also last longer. Many carmakers recommend changing synthetic blend oil every 5,000 miles or 6 months, whichever comes first. But how often to change synthetic blend oil? Let’s observe this in more detail.

What is Synthetic Blend Oil?

There are a few different types of motor oil used in vehicles today. The most common type is synthetic blend oil. This type of motor oil is a mixture of conventional motor oil and synthetic oil. The ratio of conventional to synthetic oil in the synthetic blend motor oil can vary, but the most common ratio is 50/50.

While the price of synthetic blend motor oil is usually cheaper than pure synthetic motor oil, it still offers many of the same benefits. These benefits include:

  • Improved fuel economy
  • Reduced engine wear
  • Protection against extreme temperatures
  • Longer lasting than conventional motor oil

Most carmakers recommend that you change your synthetic blend motor oil every 5,000 miles or 6 months, whichever comes first.

How is Synthetic Blend Oil Made?

Synthetic oils are made from a variety of hydrocarbons and other molecules. The most common hydrocarbon is propylene, which is derived from natural gas or petroleum. Other hydrocarbons such as butylene, pentylene, and hexylene can also be used. In addition to hydrocarbons, molecules such as sulfur, phosphorus, or nitrogen may be added to improve the properties of the synthetic oil.

Synthetic oils were first developed for use in aircraft engines because they can withstand higher temperatures and stress than conventional oils. Today, they are used in a variety of applications, including automobile engines, where they provide superior protection against wear, corrosion, and oil breakdown.

Is Synthetic Blend Oil Good?

There are several benefits that come with using synthetic blend oil in your car. One of the main benefits is that it can help your car’s engine run more smoothly. In addition, synthetic blend oil can also help improve fuel economy and extend the life of your car’s engine.

How often to change synthetic blend oil?

If you own a car, you know that one of the most important things you can do to keep it running smoothly is to change the oil regularly. But how often to change synthetic blend oil? Let’s take a look.

Synthetic blend oil change interval?

The most important factor in how often to change your synthetic blend oil is the mileage on your car. If you only drive your car a few thousand miles a year, you can probably go up to 7,500 or even 10,000 miles between changes. However, if you put a lot of miles on your car every year, you should change your synthetic blend oil more often. A good rule of thumb is to change it every 3,000 to 5,000 miles, or at the manufacturer’s recommended interval, whichever is shorter.

You should also take into account the age and model of your car. Older cars with high mileage may need more frequent changes, even if you don’t drive them very often. Likewise, newer cars with lower mileage can probably go longer between oil changes.

If you’re unsure how often to change your synthetic blend oil, consult your owner’s manual or ask a qualified mechanic. They will be able to advise you based on the make and model of your car as well as your driving habits.

Frequently Asked Questions

1. Should I use synthetic oil or blend?

Full synthetic oils are the best choice if you can afford them. Almost any engine can benefit from it. More frequent oil changes and deposits can be avoided by using synthetic oil. Unlike synthetic oil, blends are usually less expensive or you can rotate between these two oils every two or three months.

2. Is synthetic blend oil good for high-mileage cars?

Oils made from synthetic compounds will improve engine protection in older vehicles with higher mileage, just like they do in new vehicles.

3. Is synthetic blend oil as good as full synthetic?

Conventional and synthetic blend motor oils provide less engine protection and performance than fully synthetic oils.

4. How often should you get an oil change with a synthetic blend?

Synthetic oil is more refined than regular car oil, which reduces friction, reduces engine sludge, and increases engine performance. Depending on the vehicle and the synthetic oil brand, you should change synthetic oil every 7,500 – 15,000 miles.

5. Is synthetic blend worth it?

Compared to a conventional oil change, it provides a far better oil life. It’s a lot cheaper than synthetic motor oil. Due to its more affordable cost, it’s sustainable to perform frequent oil changes and has better fuel economy.

6. Does it hurt to change from synthetic blend to full synthetic?

The engine can be switched between synthetic and conventional oil without damaging the engine, as synthetic oils typically provide better protection than conventional oils.

7. Is it OK to use synthetic blend oil instead of full synthetic?

Since synthetic blends are a mix of both types of oil, switching between them is probably safe. You should, however, consult your owner’s manual to determine the type of oil you should use.

8. Can you go 5000 miles on synthetic blend oil?

Even after 5000 miles, synthetic blends are durable and will not break down. The filtration systems on newer cars are also better, so you can safely drive for 5000 miles without changing the oil. It is also possible to run 5000-mile oil changes in cars with more than five quarts of capacity.

Conclusion

The question of how often to change your oil is a hotly debated topic, with carmakers and oil companies giving conflicting advice. The answer, as with most things in life, probably lies somewhere in the middle.

Most carmakers now recommend that you change your synthetic blend oil every 7,500 miles or so. However, many oil companies say that you can go much longer between changes – sometimes as much as 10,000 or even 15,000 miles.

If you’re wondering what the right answer is for you, it probably depends on a few factors. If you drive primarily short distances in stop-and-go traffic, you may need to change your oil more frequently than someone who primarily drives on the highway. Likewise, if you have an older car with higher mileage, you may need to change your oil more often than someone with a newer car.

At the end of the day, it’s probably best to err on the side of caution and change your synthetic blend oil every 7,500 miles or so. This will help ensure that your engine stays properly lubricated and runs smoothly for years to come.
